Scaling for success: WinZO’s event-driven automation for orchestrating AWS resources

This article describes how WinZO, a multi-lingual skill-gaming platform in India, developed an automated, event-driven solution called "ZOScaler" to orchestrate scaling of AWS resources for their microservices during high-traffic events like tournaments and matches.

Specifically, the article covers:

• Challenges with traditional scaling practices like granularity constraints, server provisioning delays, and load balancer pre-warming
• WinZO's goals for the solution, including holistic scaling beyond ECS and EC2, configuration-driven microservices scaling, automated pre-provisioning, and load balancer pre-warming
• Architecture of the ZOScaler solution using AWS Lambda, Amazon CloudWatch Events, ECS application autoscaling, and Amazon DynamoDB
• Functionality of the three core Lambda functions: Scale-Up, Scale-Up Notifier, and Scale-Down
• Integration with Atlassian's Opsgenie for alerting and monitoring
• Benefits achieved, including maintaining uninterrupted service, optimizing resource usage, and cost savings
• Recommendation for AWS Countdown service to complement ZOScaler's capabilities
• Conclusion highlighting ZOScaler's success and WinZO's preparedness for future high-traffic events
